The gas handling capability is used to handle mainly liquid gas (LPG) and other hydrocarbon liquidate reshipment points and large gas depots, fire extinguishing plants sprinkling and irrigation plants emptying of fuel trucks filling of high tanks, refueling cars. Centrifugal pumps of the series UEA with special NPSH inducer stage are applied for trouble-free pumping under unfavorable conditions at suction side. A special priming stage is able to absorb eventually existing vapour from the suction side. The capability of the pumps in this series to handle liquids at the boiling point, allows a wide-ranging application when handling: • LPG • Hydrocarbon condensates • Hydrocarbon liquefied gases
Design Horizontal centrifugal pumps of the segmental type with closed impellers and a suction stage. The suction stage is installed at discharge side. It is arranged in parallel to the last liquid handling stage and operates acc. to the sucking-through principle. The design UEA has an axial inlet with NPSH inducer stage. The axial thrust is compensated by single-impeller relief. The remaining axial thrust is compensated by antifriction bearings of sufficient size. The vertically to the axis divided casings are sealed by O-rings and connected through external casing connection screws.
Construction Casing pressure: max. 40 bar up to size 8000 from -40 °C to 120 °C max. 25 bar up to size 10000 from -40 °C to 120 °C Pressure stages for higher temperatures acc. DIN EN 764-1
Please note: Technical rules and safety rules. Casing pressure = zero delivery head + pos. suction pressure
Position of the branches: Suction flange axially and discharge flange radially upwards.
Flanges: At suction and discharge side the flanges correspond to DIN EN 1092 PN 25 and PN 40. Flange design with groove to DIN EN 1092 or bored to ASME B 16.5 possible.
Hydraulics: Centrifugal hydraulic with special NPSH-impeller and gas priming stage.
Bearings: At suction side a liquid surrounded sleeve bearing, at discharge side grease lubricated inclined ball bearings as per DIN 628. The designation of this construction:.A First grease filling for antifriction bearing is made in the factory.
Sense of rotation: Clockwise when looking at the pump from the drive end.
Shaft sealing: The shaft can be sealed either by single mechanical seal or by double mechanical seal.
Special for liquid gas: Designation DNE: Flowserve EUROPAC 610 (balanced, internal
flushed) standard single mechanical seal with throttle bush for leakage control. Temperature range: from -40 °C to 120 °C max. 40 bar
Designation RBG: Flowserve EUROPAC 610/610 (balanced, internal or external flushed), acc. API 682 Plan 52 in tandem arrangement Temperature range: from -25 °C to 120 °C max. 40 bar
Designation XEY: Burgmann Cartex DE (balanced, external flushed) double mechanical seal in back to back arrangement acc. API 682 Plan 53 (optional Plan 52 for tandem arrangement) Temperature range: from -40 °C to 120 °C max. 25 bar
